本文整理了Java中org.osgi.framework.hooks.weaving.WovenClass.getBytes()方法的一些代码示例,展示了WovenClass.getBytes()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台,是从一些精选项目中提取出来的代码,具有较强的参考意义,能在一定程度帮忙到你。WovenClass.getBytes()方法的具体详情如下:
包路径:org.osgi.framework.hooks.weaving.WovenClass
类名称:WovenClass
方法名:getBytes

WovenClass.getBytes介绍

[英]Returns the class file bytes to be used to define the WovenClass#getClassName() class.

While in the #TRANSFORMING state, this method returns a reference to the class files byte array contained in this object. After leaving the #TRANSFORMING state, this woven class can no longer be transformed and a copy of the class file byte array is returned.
[中]返回用于定义WovenClass#getClassName()类的类文件字节。
在#转换状态下,此方法返回对该对象中包含的类文件字节数组的引用。离开#转换状态后,这个编织类将无法再被转换,并返回类文件字节数组的副本。
